Calculating Max Gap with Flatness?

Calculating Max Gap with Flatness?

Calculating Max Gap with Flatness?

(OP)
Hi,

I'm reviewing a report where they are trying to determine the max gap between two plates in contact.  

They use the equation (F1 + F2)/2 = Maxgap.  Where, F1 and F2 are the flatness of the two plates.

Does this make sense to anyone?  Do things change if there is a force pressing these two plates together?

I would think that the max gap equals the sum of the two flatnesses, and not the average.

Thanks,
Dummi

RE: Calculating Max Gap with Flatness?

I agree with you.  The max gap would be the sum of the flatnesses.  If there is a force pressing the two together... all bets are off.  Now we are talking a material stress, deflection issue.
